SPECIFICATION forming' part of Letters `Patent No. 227,841, dated May 18, 1880.

Application filed February24, 1880.

To all 'whom t may concern v Be it known that I, IsRAIL L. RosENFELD, of the city, county, and State of New York, have `invented a new and useful Improvement in Snow-Flows, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a longitudinal vertical 1o section of my apparatus. Fig. 2 is a horizontal section thereof. Fig. 3 is an end view of the same. Fig. 4L is a detail view of parts.

Similar letters indicate correspon din g parts. My invention relates to plows for removing snow from railroads, and has for its object the production of an apparatus adapted to the removal of snow from cuts -or inclosed spaces, as well as other portions of a road. It consists in certain novel combinations of zo parts, hereinafterfully described, and pointed out in the claims, a preliminary description thereof being therefore deemed unnecessary.

In the drawings, the letter A designates a platform, which is made of a convenient length z 5 and preferably wider than the gage of the road, while it is -inclined inV a longitudinal direction, the lower part or end thereof constitutin g the head or front ofthe plow and being close to the rails but running freely over them. 3o This inclined platform A is mounted onta truck, of which a are the wheels and b the axles, and above the platform are arranged two (more or less) clearers or sweepers, BB, which, in this example, consist, respectively,

` 3 5 of a shaft, c, and a seriesiof blades, d, and both of which receive a revolving motion from the rear truck-axle, b, by gearing next described,

so that they are adapted to throw from the platform the snow that is taken up thereon, 4o as hereinafter explained.

The motion of the rear truck-axle, b, is transmitted to the shafts of the clearers B B through the medium of vertical shafts or spindles() C, which are geared with the truck-axle by oogwheels D, E, and F, and geared with the respective `clearer-shafts by `cog-wheels 'G `or YG and QH. The wheels Eare transfer-wheels, and are arranged to be thrown out fof gear by a adjustable in a vertical direction, so that the 5 5,

clearers may be set or moved to different lev- `els-namely, toward or away from the platform A-in order to adapt the same to the height of the snow on the platform.

In order that the clearer-shafts `may remain 6o in gear with their driving-spindles C `C when the clearers B B are set up or down by means of their adjustable bearings I J J, the wheels Gr G', either of which acts on thewheel H at the rear en d of the clearer-sh afts, are arranged 6 5 to move with the clearers in a vertical direction, this purpose being accomplished by arranging the wheels G G' on feather-keys e, so that they are adapted to slide on the spindles,

and attaching to the block-bearings J J, re- 7o spectively, an arm, f, for holding the wheels G G in their positions on the spindles.

The cross-head I, forming the bearings for the forward ends of the clearer-shafts, `is arranged to slide on a standard, K, rising from the platform A, and to the same is connected one end of a chain or rope, g, which runs over pulleys h, and the other end of which is connected to a drum or windlass, L, so that 4by turning the latter in one or the other direction, 8o and thereby winding up or unwinding the chain, the cross-head I, together with the forward ends of the shafts carrying the clearers, can be raised or lowered.

rlhe blocks or boxes J J, forming the bear- 85 ings for the rear ends of the clearer-shafts, are arranged to slide in Vertical guidewayst' fi, and are each connected to an endless chain or rope,

j, running over pulleys k 7c, so that turning either of these pulleys in one or the other di- 9o rection the block-bearings are raised or lowered by means of .the endless chains, with a like adjustment of the rear ends of theclearers,

rIlhe lower pulleys to the endless chains j j are mounted on shafts O O, which respectively carry a cog-wheel, l, meshing with a pinion, m, on whose shaft is mounted a crank, n, so that a revolving motion can be imparted to the pulley-shafts for the purpose of operating the adjusting-chains jj by means of the cranks.

rIhe pulley-shafts O O are each geared with a shaft, P,'carrying the drum L, by means of a chain or rope, o, ruiming over pulleys p 1:,s0 that the drum-shaft P revolves with the pulley-sh afts. An important result of this arrangement is that the bearings I J kJ at'both ends of the clearers B B are set simultaneously, another result being that both of the pulleyshafts O revolve whether the power is applied to one or the other of them, since the motion of one is transmitted to the other through the drum-shaft I?. Provision is made, however, for setting the bearings I J J also independently of each other, as for regulating the angle of the clearers B B-namely, by mounting the drum-shaft 'P andthe shafts of the upper pulleys to the endless chains j j in boxes q q', which are held by set-screws r r', and are thereby adapted to be set to slacken the chains o o or the chainsjj.

In order to permit the setting of the clearers B B to various angles their shafts are swivelled at each end, as at s s'.

The guideways it'for the block-bearings J J are formed ina wall, Q, which extends across the, platform A at the upper or back part thereof, and serves to separate and protect the gearing and paraphernalia for driving and setting the clearers from the snow received on the platform.

With the guideways it may be combined spring-slides for closing the space between them without interfering with the adjustment ofthe block-bearings.

It is desirable, under certain conditions, that thcclearers B B revolve in one and the same direction, whether the apparatus move forward or backward, and the object of the two wheels G Gron the driving-spindles C C is to render reversible the direction of rotation of the clearers independently of the direction of movement of the apparatus. To accomplish this purpose the wheels G G of each spindle are placed above and below the wheel H,in a position to gear therewith, but are held a sut'- icient distance apart from each other, as by a collar, t, interposed between them, so that when one of such wheels is in gear with the wheel H the other remains out of gear therewith, as shown in Fig. l, and the arm j', for supporting the wheels on their spindle, is subjected to .the action of a set-screw, a. This set-screw is a fixture of the respective blocks J J, and by its means the arm f may be elevated or lowered,whereby either of the wheels G G is thrown in gear with the wheel H, and the clearers B B are revolved in one or the other direction to any direction of movement of the apparatus.

At or near the forward end of the inclined platform A is located a head-gate, It, whose function is to retain the snow on the platform in the back movement of the apparatus. This head-gate is movable in a vertical direction, and is operated by means of a chain or rope, c, which runs over pulleys w, and is connected to awindlass, S,havin g combined therewith a ratchet-wheel, and stop-pawl y. For the purpose of supporting and guiding the head-gate B it is constructed with side arms, T T, which extend rearwardly from the upper part thereof, and are pivoted to brackets U on the wall Q, so as to swing in a vertical plane.

On opposite sides, and on a'rear portion of the apparatus, are verticale win gs V V. The position of these wings is at `the upper end of the platform A and opposite td theback wall, Q, from the ends of which latter they extend rearwardly and outwardly, and to which they are attached by vertical hinge-joints Z, so that they are adapted to be swung to an outer or normal position, or to be swung inward, as when they are not in use. For the purpose of sustaining the wings V in an outer position they have attached thereto braces WV, while for locking the wings in an inner position they have combined therewith catches X.

In their inner or closed positions the wings V V bear against posts Y, which are slotted for the passage of the braces W through them, and form the supports for the catches X. These catches X consist of vertical slides, which are guided on the posts Y, and are subjected to the action of springs, having a tendency to force the same to a lower or locking position, while they are provided with slots a0, whereby they engage the braces W to hold shut the wings. Y

.In applying my apparatus to the removal of snow from a railroad-cut the head-gate R is lifted, as indicated in dotted outline in Fig. 1, to free the forward end of the inclined platform A, and the apparatus is run into the snow, the clearers B B having previously been brought to an upper position and having been thrown out of gear. In this manner the snow lying along the line of the road is taken upon the platform A, and when the latter is full the head-gate R is allowed to descend, whereby the snow resting on the platform is severed from the 'mass in advance of the plow. The apparatus is then drawn backward, in which motion the snow is held on the platform by the head-gate It, and when the apparatus reaches a part of the road suitable for discharging the load of snow the head-gate is lifted and the clearers B B are thrown in gear, while their bearings arey gradually lowered, so that the clearers receive a compound revolving and downward motion, and free the platform of its load.

It is understood that prior to starting the clearers B B the reversing-gear is set to produce the proper revolution of the clearersnamely, to throw the snow off the platformand when the apparatus is used on a road having a single track the clearers may be made to IOO IIO

revolve in op'posite directions for throwing the A snow to opposite sides of the road; but when it is used on a road having a double track the elearers are both made to revolve in one and the same direct-ion for throwing the snow to one side of the road only, thereby avoiding `its being thrown from one track to another.

The foregoing operation. is repeated until the cut has been entirely cleared of snow.

If it is desired todeposit the load of snow at any one certain spot, provision is made for operating the clearers B B by other means than the truck-axle, as by hand. When my apparatus is used on roads built on plains or highways the head-gate B is permanently elevated, or the same may be omitted, and the clearers B B are set to a short distance above the platform A, the operation in that case being to take up the snow on the platform and throw the same to one or both sides of the road as the apparatus advances.

In the forward motion of the plow the win gs V V are set to an outer or normal position, and by their means the snow displaced by the action of the clearers B B is compacted, so that it is not liable to fall back' on the track; but when the whole is moved backward the wings are shut, so as to lie close up against the sides of the apparatus and run free of interruption from the snow.

What I claim as. new, and desire to secure by Letters Patent, is i l'. In a snow-plow, the combination of alongitudinally -inclined platform mounted on a wheeled truck, longitudinal revolving clearers arranged above the platform, vertically-adjustable bea-rin gs to the clearer-shafts, and adjusting mechanism acting' simultaneously on the bearings at both ends of the clearer-shafts, the whole constructed and adapted to operate substantially as described.

2. In a snow-plow, the combination of a longitudinally -inclined platform mounted on a wheeled truek,longitudinal revolving clearers arranged above the platform, vertically-adjustable bearings to the clearershafts, and gearing adapted to transmit motion from one of the truck-axles to the clearer-shafts, so arranged that the latter may be moved to different levels by means of their bearings without being thrown out of gear, the whole constructed and adapted to operate substantially as described.

3. In a snow-plow, the combination of a longitudinally-inclined platform mounted on a wheeled truck, longitudinal revolving clearers above the platform, and gearing adapted'to transmit motion from one of the truck-axlesv gitudinally-inclined platform mounted von a wheeled truck, longitudinal revolving elearers arranged above the platform, a head-gate constructed with side arms pivoted to swing in a vertical plane for raising and lowering the head-gate, and means for elevating the headgate, the whole constructed and adapted to operate substantially as described.

6. In a snow-plow, the combination of a 1011- gitudinally-inclined platform mounted on a wheeled truck, longitudinal revolving clearers above the plat-form, and vertical wings arrangedon opposite sides and on a rear portion of the apparatus, substantially "as described, for the purpose of compacting the snow.

7. In a snow-plow, the combination of a longitudinallyinclined platform mounted on a wheeled truck, longitudinal revolving clearers arranged above the platform, side wings mounted on vertical hinge-joints, braces attached to the side wings for sustaining the same in their outer or normal positions, and catches for locking the wings in an inner position, the whole constructed and adapted to operate substantially as described.

In testimony that I claimthe foregoing I i have hereunto set my hand and seal this 31st day of January, 1879. i
